Checkpoints are used to store the specific states of processes in stable storage.When distributed systems fail, the systems can recover to a global consistency state from specific checkpoints rather than the beginning states of all involved processes.There are many kinds of checkpointing strategies suggested for distributed systems.However, the existing checkpointing protocols proposed for the traditional distributed systems are not suitable for mobile networks due to the unique characteristics such as low storage capacity, limited bandwidth, frequent disconnection, etc.Therefore, some researchers have proposed many new checkpointing strategies for mobile networks.This paper intends to give a summary of them.
